Crater of Diamonds State Park is located just to the south.

The guard cells surround each stoma in a plant cell. They regulate  the opening and closing of stomata to facilitate gas exchange and  control transpiration in plants.
Just like the Cell Wall of a plant cell, our Cell Wall Gate protects the amusement park! The Cell Membrane Security Check The Chloroplast Workers We have an amazing staff her at Plant Playland! The Chloroplasts workers use their energy to drive and keep all of our guests happy! These workers supply energy just how the chloroplasts of a plant cell supply the cell with energy for life. If there was no chloroplast workers the the amusement park would not be able to run on its own! Plant Cell Playland Before going into the park every person has to go through our security check. This is because, just like a plant cell, we wouldn't want anyone or anything who didn't belong coming into our park!
